The observed lines are from M. Bogey, C. Demuynck, J. L. Destombes and
H. Dubus, 1987, J. Mol. Spect. {\bf 122}, 313.
	
The dipole moment for C$_3$H$_2$ was determined by H. Kanata, S.
Yamamoto and S. Saito, 1987, Chem. Phys. Lett. {\bf 140}, 221. The
dipole has been rotated according to the structure of Bogey {\it et
al.} to get the a and b components.
